The Winnipeg Blue Bombers will have to deal with Anthony Calvillo this weekend as they pursue a playoff spot.

The league's top-rated quarterback, who missed last Saturday's 41-24 loss to Winnipeg because of a strained calf, will play in the rematch at Molson Stadium on Sunday.

"I"m feeling great, and I'm definitely going to be playing this weekend," Calvillo said yesterday in a phone interview.

The Alouettes are also expected to have three defensive starters back in the fold on Sunday, according to the Montreal Gazette. Linebackers Diamond Ferri (flu) and Shea Emry (concussion), and cornerback Davis Sanchez (hamstring) are all pegged to return.

INFIRMARY UPDATE: Wide receiver Adarius Bowman (knee) was nowhere to be seen yesterday, which means he won't play in Montreal, but head coach Mike Kelly expects right guard Ryan Donnelly (knee) to be able to suit up on Sunday.

Neither has practised this week.

"Donnelly should be fine," Kelly said. "I had a nice talk with Donnelly this morning, and we have to be smart about how we handle a veteran like that. But he'll be ready to play."

Donnelly started last Saturday's game against Montreal, but sixth O-lineman Luke Fritz finished it.

Slotback Terrence Edwards (hamstring) also sat out yesterday, but Kelly said he'll be back on the field today.

Otis Amey or Dudley Guice Jr. will draw into the lineup in place of Bowman.

NEW BLOOD: With Donnelly on the sidelines, the Bombers had been operating with just six offensive linemen in practice this week.

They increased that number to seven yesterday with the addition of Saskatchewan native Ryan Ackerman, a fourth-round draft pick of the Roughriders in 2007, to their practice roster.

"I'm super pumped about it," Ackerman said. "I'm very excited I'm getting another opportunity. Things didn't go the way I wanted them to back home."

Ackerman, who was Brendon LaBatte's teammate at the University of Regina, had unsuccessful tryouts with the Riders in 2007 and 2008.

SCOREBOARD WATCHING: Tonight's clash at Commonwealth Stadium between the Edmonton Eskimos and Toronto Argonauts will have a significant impact on Winnipeg's post-season pursuit.

If the Eskimos win tonight and the Bombers lose on Sunday, Winnipeg would have to beat Hamilton on Nov. 8 to nab a playoff spot.

However, Winnipeg would clinch a post-season berth this weekend if it beats Montreal on Sunday and Edmonton loses tonight.
